Maymun bin Mihran (may Allah have mercy on him) said that Sayyiduna Umar (may Allah be pleased with him) sent Sayyiduna Hudhayfah bin al-Yaman (may Allah be pleased with him) and Sayyiduna Ibn Hunayf (may Allah be pleased with him), and the two of them assessed the jizyah upon the people of al-Sawad. They both said: "Whoever among the people of al-Sawad does not come and have his neck sealed, the covenant of protection is withdrawn from him."
